Ok so i was in this plane about to go somewhere but the place wasn't even a an airport.

I dont remember much about my dream but i do remember seeing my dream journal in the dream it looked the same but the stuff i wrote in the the cover page that says "dream journal" in the dream it had something else. In the dream i was like ' what this is weird i don't remember naming it that'. And now that im awake I'm thinking of myself that could have gotten me lucid.

I have one question:

how can i increase my self awareness so I can no when I'm dreaming by seeing dream signs?
